hashpower distributed world wide
statum servers  distributed world wide
domain names not .cn, but .com meaning not chinese
administrators distributed world wide.

you do realise that your concern is out dated. the pools mitigated your concern about 2 years ago.

chinese government cannot take down the domains because they are not .cn
chinese goverments cannot slap the admin because the admin are dotted around the world
chinese goverments cannot take down the statum servers because they are dotted around the world
chinese goverments cannot shut off 51%-90% of hashpower because 51%-90% of hash power IS NOT IN CHINA!!

you are about two years too late.
the so called chinese pools have already adapted and mitigated the risks.

your issues have already been addressed and the issues you raise are resolved.

you would actually have a valid point if:
domains ended .cn
stratum servers only existed in china
farms were not in mongolia, Tibet, Finland, Iceland, and the Republic of Georgia and the rest of the world
administrators were all in one building in china.

but for all 4 points. those have been addressed ages ago
